OpenAI Swarm is completely free with 10 features included. No paid tiers offered, making it perfect for budget-conscious users.
No. OpenAI officially deprecated Swarm in March 2026 and strongly recommends the OpenAI Agents SDK for all new projects. The Agents SDK provides the same educational value with production-grade features, ongoing support, and active development.
Swarm was intentionally minimal for education with just Agent + Handoff concepts. The Agents SDK builds on these foundations while adding state management, error handling, observability, security guardrails, and production features required for real applications.
Yes, but OpenAI recommends learning directly through the Agents SDK instead. The SDK provides the same foundational concepts with modern capabilities, ensuring your learning translates directly to production-ready development skills.
Absolutely. OpenAI provides migration guidance, and the core Agent and Handoff patterns translate directly. You'll gain production features, ongoing support, and compatibility with OpenAI's latest multi-agent developments.
Both frameworks are free and open source. Costs come from OpenAI API usage for language model calls. The Agents SDK may actually be more cost-effective for complex applications due to better state management reducing redundant API calls.
The Agents SDK includes essential production features that Swarm intentionally lacked: persistent state management, comprehensive error handling, observability and monitoring, security guardrails, enterprise integrations, and active maintenance from OpenAI.
It's completely free — no credit card required.
